I have a new JVT-69, and just updated to the latest firmware (1.9) -- and when the process was finished, the LED on my Model Selector knob was glowing green.
Unplugging the guitar from the VDI cable and plugging it back in changed the LED to white.
So, does anyone have a list of what the different LED colors/flashes indicate? I've read the manual a couple of times, and see where it changes depending on if you're doing the virtual capo thing, but nothing about a green indicator.
